Definitions

  • This invention relates to gaskets of the kind comprising an essentially solid sheet metal core, into which are fitted eyelets to seal around the margins of various apertures defined in the core; the core is usually made of two separate, superposed metal layers or sheets fastened together.
  • the eyelets commonly used are typically also of metal for sealing high temperatures and pressures such as are encountered in the combustion chambers of internal combustion engines.
  • the same gasket may also have water and/or oil passageways through it and for sealing these it will generally be necessary to use a different type of seal, typically of rubber. It is now common practice to apply such rubber seals by printing them onto each side of the gasket. This calls for precision printing and control.
  • Such grommets or bushes will herein be referred to as "grommets", for convenience. This invention is particularly concerned with such grommets and with their installation.
  • the grommets required for a particular gasket are moulded integrally with a connecting web of polymeric material, the configuration of which is such that all of the grommets connected by it are so disposed relative to one another that they can be installed into the gasket in a single operation without rupturing the web.
  • the grommets for a particular gasket are moulded together and thereafter incorporated into the gasket along with their connecting web, the latter being sandwiched between two metal plates which constitute the gasket core, prior to the fitting of metal eyelets into other gasket apertures, to hold the assembly together.
  • the connecting web is thus a non-functional component of the finished gasket, because its contribution to the sealing performance is minimal. No adhesive is required to install the web, as would be required for a conventional laminate of gasket material.
  • "Polymeric material" in this present context includes any suitable resilient material, whether a conventional rubber, or a plastics material having sufficient resilience to act as a seal.
  • the presence of the web ensures easy/accurate location of the grommets, particularly under automatic or semi-automatic assembly conditions. Because moulding lends itself to making grommets of several different sizes/thicknesses in a single operation it is no longer necessary to stock a range of individual grommets of different sizes in boxes at the installation/assembly point. The risk of an operative accidentally using the wrong size of grommet is therefore eliminated.
  • the presence of the connecting web in the finished gasket assembly may to some extent reduce lateral spreading of the grommets under pressure, although as stated earlier, it is not intended to be a functional part of the finished product.
  • the grommets and their connecting web may be moulded in continuous sheet form, enabling the latter to be slit into sections, each of which contains all of the grommets for a particular gasket.
  • some gasket constructions may require the use of more than one such section, according to size and configuration of the end product.
  • the two coolant passageways, 6 and 7 have rubber grommets, 10 and 11 respectively, of different sizes. These grommets are to provide seals around the apertures 6 and 7 in use in an automotive cylinder head.
  • the grommets are integral with connecting web portions 12, 13, 14, having been moulded integrally with the latter.
